To all whom it may concern: p 4

Be it known that I, ARNOLD V. BROWN, a citizen of the United States,residing at .VVorcester, in the county of Worcester and 5 State ofMassachusetts, have invented a new and useful Buckle Base, of whichthefol i s, aspe fieat-ion-ifl This invention relates to a base for abuckle for use on hose supporters, suspenders, and other articles ofpersonal wear for binding two pieces of tape or the like together.

The principal objects of the invention are to provide a base for theclamping plate in such form that the base can be stamped out of sheetmetal with a pair of arms located adjacent to the ends of the base andin the plane thereof, and these arms then can be bent up from the baseto form two opposite 2O pivots in alignment with each other for theclamping plate; to provide these parts in such form that there will bevery little metal wasted in the process of stamping out the parts, andthe arms can be bent up very readily and inexpensively so that the edgesof the buckle are smooth all around and without any projections; and toprovide a construction of the base that will be very inexpensive both asto the amount of material used and the operation of producing it.

Reference is to be had to the accompanying drawings in which Fig. l is aplan of a blank stamped out fiat from which the buckle is to be made;

Fig. 2 is an end view of the same;

Fig. 3 is a View similar to Fig. 1 showing the base in its complete formmade from said blank;

F ig. 4 is an end view of the same;

Fig. 5 is an edge View of the same showing the clamping plate inposition, that is, it shows the complete buckle; and

Fig. 6 is a perspective View of the base without the clamping plate.

In order to secure the above mentioned advantages, I stamp out of'apiece of sufficiently thick sheet metal a flat plate 10, which is toconstitute the base plate of the buckle. This is provided in whatevershape may be desired, and at its ends are two opsit'ely projecting arms11. One edge of each of these arms is in alignment with the edge of thebase plate 10, and there is no need-of these arms extending beyond thisline. Each .one of them extends inwardly toward the opposite edge of thebase and then the two ends 2;;9fi-fihese rms, Xtend1'i 1 -r y towardeach other and in alignment. These arms, 7

out of a piece of sheet metal, are located just beyond the ends of theplate and project toward them so that very .little'metal is wasted inthe stamping operation, not much more than would be wasted with thatparticular shape of base plate if the arms were not used in fact. Thisstamping having been made it is put into a bending die or otherapparatus and the two arms 11 are twisted at the points where they jointhe base 10 around into a plane substantially at right angles to thatbase, so that both of them are in the same plane, and the twoprojections 12 extend toward each other. These two projections then arein alignment and constitute the pivots on which the eyes 13 of theclamping plate 14 are mounted to permit the pivotal motion of thisclamping plate which is required in a buckle of this character.

It is to be noted that the plane in'which the arms 11 and pivot ends 12arelocated in the completed article is preferably not exactly at rightangles to the base plate 10, but at an angle slightly less acute. Thisis to bring the pivots over the base plate instead of having them overthe edge thereof. The buckle is used in the usual way as will beunderstood. The two pivot ends 12 are all that is needed to hold theclamping plate against removal as it is mounted on them by bending itstwo eyes over them in the usual way.

By providing for manufacturing the device as stated the loss ofconsiderable metal in the stamping operation is avoided, each base platebeing stamped out of a rectangular piece, only very small portions ofwhich are discarded and the dimensions of which are at a minimum forthis kind of a device. The arms which project out of the plane of thebase plate are formed from portions of the blank, most of which wouldhave to be thrown away even if the arms were formed in some other way onaccount of the fact that the ends of the base plate converge. Such abase plate is smooth at the edges and entirely without projections afterit is finished. It is sufliciently strong for the purpose intended anddurable, and the cost of manufacture and stock is very materiallyreduced by this procedure.

Althoughl haveillustrated and described only a single form, of theinvention I am aware of the fact that modifications can be made thereinby any personskilled in the art without departing from the scope of theinvention as expressed in the claim; 'Therefore I do not wish to belimited to all the details" of construction herein shown and described,but what I jcl ai m is:%

'Asan article of manufacture, a blank for ab'uckle base plate comprisinga flat plate of sheet metalfurni's'hing a broad surface for receivingand supporting a tape thereon in "fiat condition, having diverging endsa d provided with two opposite flat arms projecting in the same plane,from the edges of said ends, at a distance from eaoh edge of said plate,said arms extending at right angles therefrom and then extendinginwardly toward each other to form two pivot ends in alignment with eachother at a dis tance from the point at which the arms are connected withthe plate, whereby said arms are located largely in the space left bythe shaping of the ends of the plate to diverge from each other andwhereby said arms can be bent away from the plate at any desired angle,leaving their ends in alignment with each other and at a distance fromthe plate to constitute pivots for a clamping plate In testimony whereofI have hereunto affixed my signature; v

ARNOLD V. BROWN.
